17. Fluoroquinolone resistance in the environment and the human gut – Analysis of bacterial DNA sequences to explore the underlying genetic mechanisms
Abstract : Fluoroquinolones (FQs) are synthetic, broad-spectrum antibiotics that target type II topoisomerases. High-level resistance is often caused by mutations in the target genes of FQs, especially in gyrA and parC. In contrast, plasmid-mediated resistance genes, such as qnr, often confer moderate levels of resistance. READ MORE
